How to use it

Add GalleryActivity to your AndroidManifest

Usage

To launch the gallery, simply use the newIntent method then start the activity.

Kotlin:

startActivity(
    GalleryActivity.newIntent(
        this,
        listOf(
            "http://www.gstatic.com/webp/gallery/1.jpg",
            "http://www.gstatic.com/webp/gallery/2.jpg",
            "http://www.gstatic.com/webp/gallery/3.jpg",
            "http://www.gstatic.com/webp/gallery/4.jpg",
            "http://www.gstatic.com/webp/gallery/5.jpg"
        )
    )
)

Java:

startActivity(
    GalleryActivity.newIntent(
        this,
        Arrays.asList(
            "http://www.gstatic.com/webp/gallery/1.jpg",
            "http://www.gstatic.com/webp/gallery/2.jpg",
            "http://www.gstatic.com/webp/gallery/3.jpg",
            "http://www.gstatic.com/webp/gallery/4.jpg",
            "http://www.gstatic.com/webp/gallery/5.jpg"
        )
    )
);

Optional Parameters

When you call newIntent, you can optionally specify:

currentImage: Initial image to display (index for imageList)

useFullBrightness: Set screen brightness to full (useful for displaying barcodes)

allowDelete: Allows user to long press to delete image. To use this feature you should startActivityForResult, and to get the updated list you can call getStringArrayListExtra(GalleryActivity.IMAGE_LIST) for the intent returned in onActivityResult.
